采用野外调查和室内分析相结合的方法，研究福建省武夷山市5种不同类型茶园土壤（黄壤、红壤、潮砂土、高山草甸土、紫色土）团聚体有机碳分布特征。结果表明：5种类型茶园土壤各粒级团聚体有机碳含量均随土壤层次的加深呈现降低的趋势；2个土层中，5种类型茶园土壤团聚体有机碳含量均以＞5 mm粒径最高，随着土壤团聚体粒径的增加，团聚体有机碳增加；黄壤、高山草甸土和紫色土茶园均以＞5 mm粒径团聚体有机碳储量和贡献率最高，而潮砂土则以＜0.25 mm粒径最高；土壤有机碳含量与各粒径团聚体有机碳含量呈极显著正相关（相关系数为0.95～0.98）。

A combined method of field investigation and laboratory analysis was conducted to study the distribution features of organic carbon in soil aggregates from different tea plantations (yellow soil, red earth, moisture sandy soil, alpine meadow soil and purple soil) in Wuyishan City. The results showed that a depth-dependent manner was found in 5 soil aggregates with the content of organic carbon decreasing higher at 0~20 cm and less at 20~40 cm. There was a positive correlation between the contents of organic carbon and particle sizes of soil aggregate and most was exhibited at >5 mm in 5 tea plantation soils. The storage and distribution ratios of organic carbon were the highest while particle size of soil aggregates>5 mm in yellow soil, alpine meadow soil and purple soil, and<0.25 mm in moisture sandy soil, respectively. From the results, the contents of organic carbon in soil have an extremely significant positive correlation with its aggregates.
